Nottingham Forest boosted their chances of securing a top-eight spot in the Europa League league phase with a 2-1 win away at Utrecht.
Sean Dyche's side made hard work of it against a team who are yet to win in this season's competition, but secured their first European away win since October 1995 courtesy of goals from Arnaud Kalimuendo and Igor Jesus, either side of an equaliser from former Swansea defender Mike van der Hoorn.
Forest started well and, for a time, it seemed it would be a case of how many they could put past Utrecht, rather than whether they could even break the deadlock.
They had eight attempts in the first 20 minutes. Strong saves from Vasilis Barkas kept out strikes from Callum Hudson-Odoi and Douglas Luiz, while Oleksandr Zinchenko fired across the face of goal from seven yards and a goalbound header from Morato was deflected over.
But Forest's inability to capitalise on their dominance gave the underdog hosts belief.
Miguel Rodriguez showed his penchant for a shot from distance; a stinging drive was batted away by John Victor and another swirled in the air before the Forest goalkeeper - deputising for Matz Sels, who missed out with a tight groin - held.
Forest took the lead early in the second half when Kalimuendo, largely anonymous until then, barged his way past two Utrecht defenders, benefitted from a fortunate ricochet and fired past Barkas from a tight angle.
Utrecht's energy levels dipped after the break, but the scoreline meant they were always in the game, and they levelled with just over 15 minutes to play when the unmarked Van der Hoorn headed in at the far post.
Dyche threw on Morgan Gibbs-White and Igor Jesus in an attempt to salvage the win - and, before long, it paid off.
Gibbs-White found Hudson-Odoi, who picked out Dan Ndoye. His header was straight at Barkas, but the ball sprung free for Jesus, who pounced in a flash to score the important winner for Forest.
Nottingham Forest Sean Dyche speaking to UEFA:
"We dominated the early periods of the second half. We conceded from a free-kick but then the reaction was fantastic, with the subs coming onto the pitch and affecting the game.
"Igor getting a goal and I'm very pleased for Kali too. Overall we were worthy of the win.
"We started very well with the ball, had a real control of it, had two or three chances and could have been one or two up.
"Then they came back into it, tested our 'keeper a couple of times, used the energy of their crowd, got the ball forward and asked questions."
Nottingham Forest's Callum Hudson-Odoi speaking to TNT Sports:
"It was difficult. Going 1-0 up, you want to maintain the lead and try and see it all the way through, but we concede. It's a sloppy goal from us, we know it as well.
"But the reaction was good, we got the second goal and we saw the game out.
"We want to go all the way to the final and try and win it, but it's a long way to that still.
"I wanted a goal, you could see that, but it's not always about scoring, it's about helping the team going forward and defensively.
"I kept saying to myself they are going to come and once they come, hopefully they will just keep flowing in nicely. I'm just enjoying playing my football. I've just got to keep working and doing the right things."
Nottingham Forest finish their Europa League league phase campaign at the end of January.
They travel to Portugal to take on Braga on January 22 and host Ferencvaros a week later on January 29.
